Definitions
- the present invention relates to a battery current sensing device having a current sensor electrically connected to the battery of a vehicle and having a measuring circuit on a printed circuit board which is electrically and mechanically connected in a fixed position relative to the current sensor such that the measuring circuit is electrically connected to the current sensor.
- DE 199 61 311 A1 (corresponds to U.S. Pat. No. 6,787,935) describes a battery current sensing device which is mechanically mounted on a pole terminal of a battery of a vehicle.
- the device includes a current sensor having a measuring resistor between contact surfaces of the sensor. Soldered connections electrically and mechanically connect the sensor to a printed circuit board (“PCB”).
- PCB printed circuit board
- the contact surfaces of the sensor are made of copper and the measuring resistor is made of manganin (i.e., an alloy of copper, manganese, and nickel).
- the sensor and the PCB have similar thermal expansion coefficients.
- a problem is that the measuring resistor of the current sensor of a battery current sensing device is subjected to severe temperature fluctuations during vehicle operation.
- the measuring resistor is cold when the vehicle has been parked in cold temperature for a long time. Upon the vehicle being started, several hundred amperes of current flow through and heat the measuring resistor. The temperature rise of the measuring resistor may exceed 100° C. causing considerable thermal expansion of the resistor.
- a typical design of a battery current sensing device includes a PCB fixedly connected (i.e., connected via non-flexible leads) to the current sensor. This design is typical as it is economical and can be manufactured easily. However, a problem arises in matching the size of the expanding measuring resistor with the PCB. That is, the non-flexible lead lines do not provide much play to accommodate the size expansion of the measuring resistor relative to the PCB.
- a solution to this problem includes making the measuring resistor and the PCB out of materials having similar coefficients of thermal expansion.
- a disadvantage with this solution is that the selection of possible materials to use for both the measuring resistor and the PCB is limited.
- this solution partially solves the problem as temperature equalization between the measuring resistor and the PCB requires a certain time with the result being that temperature-related mechanical stresses cannot be avoided.
- the PCB should not assume the temperature of the measuring resistor, which can be quite high, to protect electronic components (e.g., a measuring circuit) on the PCB.
- An object of the present invention is a battery current sensing device having a current sensor electrically connected to a battery and electrically and mechanically connected to a circuit substrate (e.g., a printed circuit board) in such a way that the problems resulting from the thermal expansion of the measuring resistor of the current sensor relative to the circuit substrate are avoided.
- a circuit substrate e.g., a printed circuit board
- the present invention provides a battery current sensing device for the battery of a vehicle.
- the battery sensing device includes a current sensor connected to the battery to receive current flow of the battery, a circuit substrate having a measuring circuit, and a connecting element having first and second ends.

- At least one of the first end and second end of the connecting element includes a press-fit contact for establishing the corresponding connection to the current sensor and the substrate.
- the present invention provides a battery current sensing device for the battery of a vehicle.
- the battery current sensing device includes a current sensor connected to the battery to receive current flow of the battery, a circuit substrate having a measuring circuit, and a plurality of connecting elements.
- Each connecting element has a first end and a second end. The first end of each connecting element is electrically and mechanically connected to the substrate and the second end of each connecting element is electrically and mechanically connected to the current sensor such that the connecting elements electrically and mechanically connect the substrate in a fixed position to the current sensor with the measuring circuit being electrically connected to the current sensor.
- the first end of each connecting element includes an elastic press-fit contact for establishing the connection to the substrate.
- the present invention provides a battery current sensing device for the battery of a vehicle.
- the battery current sensing device includes a current sensor connected to the battery to receive current flow of the battery, a circuit substrate having a measuring circuit, and a plurality of connecting elements.
- Each connecting element has a first end and a second end. The first end of each connecting element is electrically and mechanically connected to the current sensor and the second end of each connecting element is electrically and mechanically connected to the substrate such that the connecting elements electrically and mechanically connect the substrate in a fixed position to the current sensor with the measuring circuit being electrically connected to the current sensor.

- a battery current sensing device in accordance with an embodiment of the present invention includes connecting elements which each have at least one press-fit contact connected to at least one of the current sensor and the circuit substrate.
- the connecting elements on account of their elastic properties resulting from the elastic effect of the press-fit contacts provide a mechanically stationary yet non-rigid mechanical and electrical connection between the circuit substrate and the current sensor. As a result, the battery current sensing device in a simple and economic manner avoids temperature-related mechanical stresses.
- the press-fit contacts of the connecting elements provide a mechanical connection having a low thermal coupling between the current sensor and the circuit substrate.
- the temperature of the circuit substrate may be matched to the average temperature of the current sensor over a long time period, and temperature peaks in the current sensor, which may occur during vehicle start-up, do not excessively heat the circuit substrate and the temperature-sensitive electronic components of the measuring circuit.
- the press-fit contacts of the connecting elements provide a simple and reversible installation of the circuit substrate to the current sensor.
- the current sensor itself may be a metal strip.
- a measuring circuit on the circuit substrate is electrically connected to the metal strip to evaluate a physical variable dependent on the battery current flow through the metal strip.
- the physical variable dependent on the current flow through the metal strip may be a magnetic field or heating resulting from the current flow.
- a simple method of current flow measurement is to consider a section of the metal strip as a measuring resistor and detect the drop in voltage at that location.
